In case you missed that little notification in your iPhone settings, iOS 7.1 is available and everyone with an Apple gadget needs to update ASAP.
New in iOS 7.1 are bug fixes, as well as improvements to the iPhone 5s' fingerprint sensor. Even better, iOS 7.1 allows anyone - even iPhone 4 users - to take advantage of CarPlay, which you can learn more about here.
Other improvements and fixes have been made to FaceTime, Siri, iTunes Radio and the calendar.
In order to update your iPhone or iPad go to Settings>>General>>Software Update.
